Title: Butt welding method for centrifugal casting tube
Inventor: MIHARA TAKAO
IPC: B23K9/02
Filed: 1977-12-09
Abstract: PURPOSE: To improve the stability of welding operation and object thickness, by forming I-shaped groove butting a pair of centrifugal casting tube along the whole length of each thickness direction and mixing the surface oxidation film of casting tube in molten pool at welding time.  
     CONSTITUTION: Nearly I-shaped groove 3 is formed by butting a pair of the centrifugal casting tubes 2, 2 and the heat pervious oxidation film 1 on the surface of the tubes 2, 2 composed of SiO 2 , MnO, Al 2 O 3  etc., is easily mixed in the molten pool 4 when plasma welding is carried out. Viscosity of the pool 4 is increased when oxides are mixed in the pool 4 and the surface tension shown in the arrow mark A, is increased and then, the influence of gravity shown in the arrow mark B, is decreased. As a result of it, the burn-through etc. are not produced because upward force acting on the pool 4 is increased. Also, the above oxides are risen to the surface as slags after the pool 4 is solidified and the above slags are useful for preventing oxidation of the bead covering outside of the bead. Moreover, excess growth of uranami is prevented by the slags sticked on the back of the bead.

Filed: 1977-12-12
Abstract: PURPOSE: To always make output voltage constant with simple structure by changing the oscillation frequency of an oscillator in accordance with the temperature of a ferro-resonance constant voltage transformer.  
     CONSTITUTION: The temperature of a core is detected by a temperature detector 10 and the oscillation frequency of an oscillator 1 is changed by this detection output. When the core temperature is high, the oscillation frequency becomes high and when low it b becomes high. In a ferro-resonance type constant voltage transformer 5, when the frequency of input voltage increases, output voltage also increases. As a result, even when the temperature changes, output voltage can be kept constant.
